INFLUENCE OF TREES.
A Consideration of Thor Rotation ia
Houses and Individual Health.


The special issueof the United States
Agricultural Department on forestry,
and many other contributions, have
shown how rainfall is affected, how the
balance of the atmosphere is disturbed.
and how climate changes from the ex-
tended and rapid removal Of forests.
There is another study of trees allied
TO this which has reference to their re-
lation to houses and to individual
health.
Both the atmosphere and the soil are
cooled and moistened by the presence
of trees. This results from the draw
ing up of the water from the subsoil
and from the exclusion Of the suns
rays. Besides this a considerable por-
ton of the rainfall collects on the
leaves and branches NJ. Fantiat has
shown that the LEAKAGE of leaf-bear-
ing trees intercepts one-third. and that
Of pine trees one-half of the rainfall,
which is afterward returned to the at
mospherc by evaporation. On the
other hand, these same leaves and
branches restrain the evaporation
of tho water which reaches the
ground. This evaporation is
nearly four times less under a
mass of foliage in forest and two and
one-third times under q mass Of pines.
than in the open. Then we have
stagnation of air from that interrupt
ton of wind currents caused by tho
foliage. 1t is, therefore, not without
reason that the sanitarian studies the
trees of the yard or lawn in their bear
ing upon individual health. Persons
of susceptible lungs, or having any
tendency to rheumatism, need to BIO
carefully guarded against such in
fluenccs. Where the foliage is dense
about houses. or where the limbs over
shadow the piazzas or roof, they
become the storage places for damp,
air. The falling leaves,
gathering from year to year,
give corresponding dampness to the
soil. while at time of foliage the sun
shine is measuably excluded. IL is
